java - 我无法让 Java .Replace 对象根据扫描仪输入更改我的字符串

Question

我正在使用扫描仪将字符串值放入 currentGuess，然后我有一个名为“alphabet”的方法，其中包含一个简单的字母字符串，我想要一个字母，无论是用户放入扫描仪的 a、b、c，用 _ 替换 Alphabtet String 中的字母或采取。这不再像以前那样发生了。我不知道我做错了什么。在“扫描仪”下方是一个名为“alphabet()”的对象；它会检查您的信件并更新列表并返回。该程序类似于拼字游戏，用户输入一个字母，然后从字母表中删除该字母。只有被替换的字母是 'abcdefg'so 7，这是 while 循环设置的值，但出于某种奇怪的原因，没有其他内容。如果我将字符串中的第一个字母设置为“h”，然后键入 h，它会改变那封信。我将为感兴趣的人提供一小部分问题代码和我的整个代码。如果有人帮助我，我会很高兴。

private static String alphabet()
{
    System.out.println("debugging:underneath alphabet string. >"+currentGuess+"<");
    for(int i=0;i<alphabet.toCharArray().length;i++){
            if(currentGuess.contains(alphabet.toCharArray()[i]+""))
            {   
                System.out.println("debugging: >"+currentGuess+"<");
                alphabet=alphabet.replace((alphabet.toCharArray()[i]+""), "test");
                
            }else if(currentGuess.contains(Vowels.toCharArray()[i]+""))
            {
            System.out.println("You have just entered a Vowel, board not affected.");
